You are in the United States and the person doing this is in Australia. You report at home, and at the same time trigger action where they actually are.
911 (police, fire, medical). Use 911 for any immediate physical danger: in-person threats, someone at your door, a credible imminent death threat, or "swatting"/active emergency. Text-to-911 is available in many but not all areas; if it fails, call. For NON-emergencies (to start a paper trail), do NOT use 911. Many areas also have 311 for non-emergency municipal services, but that is not a guaranteed police-report line.
Most people here are not in an active emergency. To start an official record, use the non-emergency steps below.
Keep doing everything below in the United States. At the same time, the fastest leverage often sits in Australia, where the person actually is.
The fastest protection lever against a perpetrator located in Australia is the eSafety Commissioner's civil removal scheme under the Online Safety Act 2021. eSafety can issue REMOVAL NOTICES to platforms and end-users under the Adult Cyber Abuse Scheme (18+), the Image-Based Abuse Scheme, the Cyberbullying Scheme (under-18) and the Online Content Scheme; non-compliant services can face civil penalties of up to 500 penalty units. For most schemes the victim must first report to the platform or service, then lodge at https://www.esafety.gov.au/report. This is a civil takedown route that runs alongside, and does not replace, a criminal police report. Note the deliberately high 'serious harm' threshold for the Adult Cyber Abuse Scheme. In parallel, where the victim fears ongoing harm, an Apprehended Violence Order (AVO) / personal safety intervention order can be sought against a locally-located perpetrator via the local court or police.
When the perpetrator is located in Australia and the victim is overseas, the foreign victim's own police refer the matter to Australian law enforcement through police-to-police channels: the foreign country's INTERPOL National Central Bureau contacts the AFP-hosted INTERPOL National Central Bureau (NCB) Canberra (within AFP International Operations, operating 24/7), which channels notices, information-sharing and assistance requests. The matter is then assessed and, for an individual harassment case, typically referred to the relevant Australian state or territory police where the perpetrator is located. For evidence-gathering or prosecution that needs formal cooperation, a Mutual Legal Assistance (MLAT) request is coordinated by the Commonwealth Attorney-General's Department under the Mutual Assistance in Criminal Matters Act 1987. A victim cannot trigger these channels directly; they ask the investigating police to route the matter through INTERPOL Canberra or MLAT.
eSafety is a civil regulator and does not prosecute, award damages, or replace police. The criminal route remains state/territory police (or the AFP for serious/transnational matters), reachable from abroad only via the police-to-police INTERPOL Canberra channel described above.
File a non-emergency report, and do the single most important thing: get your report / reference / occurrence number. That number is the key that unlocks platforms, prosecutors, employers and protective orders.
Call the non-emergency line or use the online portal to file a report documenting each incident (dates, screenshots, URLs, usernames, the offender's identity if known). Ask for the report/case number and a copy of the report. If the conduct crosses state lines (most online cases), say so; the department may coordinate with the FBI. Keep your own evidence log too.
Official U.S. government page that directs victims to local police for most crimes and to the correct federal agency for cyber/identity crimes. It directs victims to search for the local law enforcement agency where the crime occurred and to FBI channels for internet crime and hate crimes. Use it to confirm which channel fits your situation.
Submit a tip describing interstate threats, cyberstalking, or doxxing. Every tip is reviewed by FBI personnel and routed to the appropriate field office or partner. This is an intake/referral channel, not a guaranteed investigation, and you generally will not get case-by-case feedback.
For identity theft / impersonation involving misuse of your personal or financial identity: file at IdentityTheft.gov to generate an FTC Identity Theft Report and a personalized recovery plan. Many police departments ask for the FTC report before/with taking a local police report; bring both together. The FTC report is itself treated as an official report for credit bureaus and most companies.
File here in addition to, not instead of, your local police report.
The FBI-run central national intake hub for cyber-enabled crime, including cyberstalking, online threats, extortion/sextortion, and online fraud. IC3 does NOT investigate complaints itself; it analyzes submissions and may refer them to federal, state, local, or international law enforcement for possible investigation. Complainants generally do not receive case-by-case updates. File even if unsure it qualifies, and file in addition to (not instead of) a local police report.
Lead federal investigative agency for interstate cyberstalking, interstate threats, extortion, and doxxing of federally protected persons. Unlike IC3, FBI field offices can open and conduct investigations. Tips via tips.fbi.gov are reviewed and routed; you can also contact your nearest field office directly.
Federal one-stop intake and recovery system for identity theft and impersonation that misuses your identity. Generates an official FTC Identity Theft Report and recovery plan. The FTC does not prosecute individual cases but feeds reports into the Consumer Sentinel database used by law enforcement.
